G.Skill's prepping optimised DDR5-6000 memory kits for AMD's Zen 4 processors

AMD's next-generation Ryzen 7000 series processors will bring major changes to the company's CPU lineup. For starters, Ryzen 7000 series CPUs will move AMD onto their new AM5 CPU platform, moving the company to DDR5 memory technology and PCIe 5.0 connectivity. AMD's Zen 4 processors will not support DDR4 memory, and that's forcing memory manufacturers to create new DDR5 memory kits for AMD's next-generation Ryzen processors. 

G.Skill are reportedly working on new DDR5-6000 memory kits for AMD's Ryzen 7000 series, memory modules that will reportedly support AMD's EXPO (EXtended Profiles for Overclocking) feature. These memory modules are designed to run at speeds that are said to be a "sweet spot" for AMD's Ryzen 7000 series memory controller. 

With their Trident Z5 "F5-6000J3038F16G" memory kits, G.Skill are reportedly offering 6,000MT/s speeds with CL30-38-38-96 timings. At this frequency, AMD's Ryzen 7000 series processors will reportedly be able to run their memory controllers/Infinity Fabric at 3,000 MHz, offering a 1:1 memory/fabric speed ratio. Higher memory frequencies will likely require AMD's Ryzen 7000 series' memory controller and Infinity Fabric to run at a slower 2:1 ratio, lowering fabric/controller speeds. 

Why optimised memory matters

In an ideal world, a Ryzen based PC would have its memory controller, infinity fabric, and memory running at the highest possible frequencies. Having super fast memory doesn't matter if your memory controller cannot keep up with it, and there are ideal speeds where you can have your memory speeds and memory controllers running in sync. 

With AMD's Ryzen 7000 series, AMD's memory/controller speeds are at their "sweet spot" when memory is running at 6,000 MT/s. In frequency terms 6,000 MT/s translates to 3,000 MHz, giving AMD's Ryzen 7000 series memory controller a 3,000 MHz sweet spot. PC enthusiasts want their memory controllers and memory frequencies as high as possible to deliver the maximum possible memory performance. Higher memory frequencies will force memory controller speeds to lower, delivering sub-optimal performance.

Let's say that you use a DDR5-6600 kit with a Ryzen 7000 series processor. If you were to run this memory at its rated speeds with a 1:1 memory/controller frequency ratio, AMD's Ryzen memory controller would need to run at 3300MHz. If AMD's memory controller cannot run that fast, a 2:1 memory/controller frequency ratio could be used, lowering AMD's memory controller frequency to 1650MHz. That lowering of memory controller frequency has performance downsides, mitigating the benefits of using higher speed memory. Running memory at "sweet spot" frequencies helps PC builders get the most performance and value out of their systems.

We expect to learn a lot more about AMD's Ryzen 7000 series processors over the next few weeks. AMD's Ryzen 7000 series is reportedly becoming available next month, moving AMD into the DDR5 era with a new CPU architecture and a new CPU platform. 

You can join the discussion on G.Skill's plans to launch "sweet-spot" Ryzen 7000 series DDR5 memory kits on the OC3D Forums.
